Meeting of January 22, 2001
Present: Ray Arnold, Peter Bosted, Don Crabb, Keith Griffioen, Steve Rock
1) Steve and Peter summarized their January 19 meeting with Steve
Williams. These included:
a) Looking at a schedule of running one experiment per year. The
order of E160/E61/E159 seems like a good one. Should be frozen at the
collaboration meeting, if consensus can be reached.
If E158 does not need extra time, the runs
would likely be in fiscal 2003, 2004, and 2005. The LCLS (free
electron laser) is not likely to be ready before 2006. After that,
they will want 9 months of running per year (incompatible with
E.S.A. running). If E158 can justify need for extra run, or if
another top priority experiment comes along, the Real Photon runs
could slip by a year or so.
b) Steve would like to avoid the last minute manpower crunch
(involving a lot of overtime) that has affected E158. The
collaboration has to minimize any design changes, and provide
the engineers with firm designs as soon as possible. This
means we should make a plan at the collaboration meeting to
identify all question marks in the setup, and find people to
come to optimal solutions as soon as possible. It is especially
important to look for any flaws early on. A good layout and list
of components is needed soon.
c) There will be a high level SLAC Project Manager to
coordinate activities. This will likely be Tim Thurston.
John Weisend will likely
be the main SLAC person working on the polarized target.
The Photon Beam will be a separate project from the experimental
setup. Dieter Walz and Ted Fieguth will manage this project.
d) We should start thinking about MOU's for building detectors.
Probably Perry Anthony will work on these.
e) there is no money for us this fiscal year, except possibly
for a few small items needed for prototyping work. Fiscal 2002
(starts October 2001) will have money at the same rate of a
few million dollars/year as SLAC has been spending in the past
few years. We should identify what major items need to be purchased,
and which can be in 2002, and which 2003. Items can be ordered
in one fiscal year, and paid for in the next, if that is when
they are delivered.
2) Don Crabb discussed target progress. He has talked with John
on the phone, and will meet with him on Feb 8 or 9. Don found that
the lead time for Roots pumps is much shorter than expected, about
4 months.
3) Keith reported on some progress in thinking about E160, but
I cannot remember what he said at the moment.
4) We discussed who would speak at the collaboration meeting.
We will try to have Steve, Peter, Don, Keith, Perry, Dieter,
Robert, and George at the very least. Steve Williams said he
will attend the meeting, and could say a few words at the
beginning. We should invite Tim Thurston to attend as well.
